IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 132,055, dated October8, 1872.

To all whom it may concern:

Be it known that I, JUSTIN OOGHRAN, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and valuableImprovement in Heating Apparatus and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingmaking a part of this specification, and 'to the letters and figures ofreference marked thereon.

The figure of the drawing is a representation of a vertical section ofmy invention.

My invention has relation to a heating apparatus. and consists in thenovel arrangement of flues for receiving cold air, allowing it to becomeheated, and thence conductingit to apartments to be warmed,substantially as hereinafter described.

Referring to the accompanying drawing, A represents a cylindricalstove-body having a door, A smoke-escape B, and register A. G designatesa serpentine or bent pipe passing upward through the floor, thence intoand through the stove, and finally out at one side near the top. Thispipe is designed to receive cold air from below the-floor. As soon asthe fire is started the air in said pipe becomes heated and rarefies,and thereby creates a strong current, which may be conducted to distantapartments to warm them. The arrangement of the pipe within thestove-body tends to expand the flame and to cause its heat thereby to bemore widely difi'used. E and F represent dampers to regulate the flow ofair. G designates an elbow connected with the lower part of the pipe 0and provided with a damper, I. The object of this pipe is to take thecold air from a room in the morning when the fire is started, so as tofacilitate the heating of the room. The top section or drum 0 of thepipe 0 is of larger dimension than the lower part, and, runnin gin ahorizontal direction, is connected with the section a projecting fromthe stove by means of a loop, b, on the latter, catching a stud, b, onthe former, as shown. This loop is to be raised when it is desired toremove the serpentine pipe.

What I claim as my invention, and desire to secure by Letters Patent, is

The stove A, consisting of the interior serpentine pipe 0 passing upwardthrough the floor, and having at its upper end the drum 0, regulators Eand F, elbow Gr provided with the damper H, the whole constructed andarranged in the manner as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JUSTIN OOCHRAN.
